Brief summary

This study is a phase I/IIa, single-center, open-labeled, randomized, controlled clinical trial. The aim of this study is to evaluate the safety and efficacy of a modified ventriculoperitoneal catheter placement using a splitable trocar for ventriculoperitoneal shunt.

Detailed description

This study is a phase I/IIa, single-center, open-labeled, randomized, controlled clinical trial. Patients hospitalized with hydrocephalus will be enrolled and randomly allocated into open mini-laparotomy group (OLG) or abdominal puncture group (APG) for insertion of the peritoneal catheter. Observe will followed for up to at least 6 months after surgery. The primary endpoint is the rate of overall shunt complication or failure within the first 6 months after surgery, and duration of the abdominal catheterization. The secondary endpoints are rate of distal shunt failure, the overall incidence of various adverse reactions, abdominal incision size, analgesic use as evaluated on Day 5 postoperatively, duration of hospital stay. Moreover, neurological function of patients (mRS, maxillary hydrocephalus scale) and CT measurement of Even index will also be evaluated.

Interventions

PROCEDUREOpen Mini-Laparotomy

A 5-cm paraumbilical skin is made, and the abdominal wall is incised in layers. The distal catheter tip is inserted into the peritoneal cavity in a craniocaudal direction, and the abdominal wound is sutured in layers.

PROCEDUREAbdominal Puncture

An about 0.5-cm paraumbilical incision made to allow introduction of a splitable trocar. The trocar is pierced through the abdominal wall into the abdominal cavity. Pull out the puncture cone, and adjust the trocar towards the pelvis. The distal catheter tip is inserted into the peritoneal cavity through the puncture cannula. Then the splitable puncture cannula is split apart and removed. The skin incision requires only one stitch.
